For windows...

fileno() is deprecated: https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/posix-fileno?view=vs-2017

Changing the -std=c*** in your makefile to -std=gnu++0x should fix your problem.

If you don't know what c++11 is you're most likely not using it anyway.

Also if you need c++11 support you can also do: -std=gnu++11 instead of -std=gnu++0x
